Hey everyone! I'm diving into a fun project where I'm trying to create a homemade robot costume, and I'd like to add some cool electronics to it. I'm not super familiar with the terms or gear needed, so I'm hoping for some advice!
Here's what I'm thinking: I want to build a chest piece that has a speaker and can play different songs based on the position of a dial—kind of like an oven dial. I want the center position to be 'off' and then have two other positions that play different MP3s.
I thought about using a 5-way rotary switch for this, but I'm not really sure how to get started with research since "3 setting music player" hasn't been that helpful. Do you think I need something like an Arduino board or a Raspberry Pi Pico for this? Is this project too advanced for someone just starting out? Any tips or guidance would be super helpful!

You've got a really interesting project on your hands! There are actually quite a few ways to approach this. One option is to use the PJRC chip that’s designed specifically for playing sounds. They usually offer evaluation boards that could be a great starting point.
But if you're more comfortable with something simpler, consider using a smartphone to handle the audio. You can design your costume to control the phone instead! Trust me, this could save you a ton of headaches. Just remember—your initial ideas might evolve as you go along!
Check out the DFPlayer Mini! You can set it up with a couple of resistors and a 3-way switch to play two different MP3 files. Keep in mind that the songs will loop while the switch is engaged. If you want to play the song just once each time you move the switch, then you’ll definitely need a small controller like an Arduino. Also, for other options, you might want to look into the 'wav trigger' from Sparkfun or on AliExpress. It's worth checking out!
